Prompt Engineering for Large Language Models

Structured prompting, few-shot examples, tool use, and output control.

Slide Visual

Overview

Prompt engineering helps guide large language models to produce accurate, reliable, and consistent outputs using structured instructions and examples.

Key Concepts

Structured Prompts

Define clear roles, goals, constraints, and formats to reduce ambiguity.

Few‑Shot Examples

Demonstrate desired outputs to help the model replicate patterns.

Tool Use

Guide the model to call APIs, run functions, or use external tools.

Output Control

Ensure consistency with formats, schemas, and explicit constraints.

Prompt Engineering Process

1. Define Objective

Identify the task and success criteria.

2. Add Constraints

Specify rules, tone, and structure.

3. Provide Examples

Demonstrate ideal outputs.

4. Enable Tools

Define tool calls or functions if needed.

5. Evaluate & Refine

Test and adjust prompts for accuracy.

Use Cases

Information Extraction

Use structured prompts to pull consistent fields from text.

Workflow Automation

Use tool-assisted prompting to execute tasks via functions.

Content Generation

Ensure tone, style, and format using output‑controlled prompts.

Prompting Approaches Compared

Basic Prompting

Quick but inconsistent results.

Structured Prompting

Improved clarity, reliability, and output control.

Few‑Shot + Tools

Highest accuracy; ideal for complex tasks and workflows.

FAQ

Why use structured prompts?

They reduce ambiguity and guide the model to consistent outputs.

When are examples helpful?

Few‑shot examples help the model learn desired patterns.

How do tool calls help?

They extend the model with actions, calculations, and external data retrieval.

How to enforce output structure?

Explicit schemas, formats, or step-by-step instructions.
